Chironius fuscus (Serpentes: Colubridae): Predation over anurans in explosive reproduction

Edelcio Muscat, Arthur Diesel Abegg, Omar M. Entiauspe-Neto


Anurans compose an important part of the diet of several species of Neotropical snakes. Here we report a predator-prey interaction involving Chironius fuscus and Ololygon argyreornata. A young individual of C. fuscus preyed three specimens of O. argyreornata, in soil, while occurred explosive reproduction of frogs. This contribution reinforces ecological data that C. fuscus forages mainly on the ground. We believe that this interaction can occur with relative frequency and that eventually arboreal frogs can compose important sample in C. fuscus’ diet, which is based on terrestrial amphibians.

Keywords: anurophagy, Colubrinae, diet, feeding habits.
